aSensitivity: percentage of positive in patient samples.
bCI: confidence interval.
cMFI: mean fluorescence intensity.
dSpecificity: percentage of negative in healthy samples.
eDifferences in the total IgG prevalence for each antigen between vivax patients and healthy individuals were calculated by Student’s t-test. A p value of < 0.05 is considered statistically significant.
